Abstract

A simple electrostatic accelerator capable of producing a monoenergetic beam of alkali metal ions at energies up to 100 kev has been used to study the range of Cs137 ions in aluminum as a function of energy. The median range (RM) increases linearly with energy as predicted from the Bohr–Nielsen equation, but has a value about twice that predicted by this equation. Furthermore, the observed straggling about the mean value is not Gaussian in shape, but consists of an asymmetric peak with a pronounced exponential "tail". The possible significance of these results is discussed. Preliminary results are given for the range of 30-kev Rb86 and Na21 ions in aluminum.
